Antiperovskite Magnetic Materials with 2p Light Elements for Future Practical Applications

“…Yu et al discussed the VCMA effect based on the first-principles calculations with various atomic-layer termination at the Fe 4 N/BaTiO 3 interface, in which the modulation of magnetic moment is associated with the magnetoelectric coupling. [231] Consider that the lattice constant of Fe 4 N is close to that of BaTiO 3 , one of the ferroelectric materials, VCMA could become a promising technology for antiperovskite materials such as Fe 4 N and Mn 4 N.…”

Magnetization reversal of perpendicular magnetic anisotropy regulated by ferroelectric polarization in CoFe3N/BaTiO3 heterostructures: first-principles calculations

“… 40 Moreover, the Mn-substitution doping at the interfacial Fe II position in the Fe 4 N/BaTiO 3 heterostructure may obtain a large ME effect. 41 In order to further improve the interfacial PMA and achieving the electric field switching of PMA, the substitute CoFe 3 N is introduced as the ferromagnetic layer of multiferroic heterostructure, which has a great application prospect for spintronics.…”
